Why Some Like It Hot: Spices Are Nature’s Meds, Scientist Says

People who live in warm climates are attracted to spicy foods because the red-hot seasonings keep people healthy, according to a scientist who takes a Darwinian approach to medicine.

“The Darwinian approach asks the question, Why are certain things the way they are, which is a complement to the approach of asking, How do things work?” said Paul Sherman, a professor of neurobiology and behavior at Cornell University in Ithaca, New York.
